What to know before buying

Listing details to confirm

Listing details are inconsistent or unconfirmed: the title claims 7 attachments and a 0.7-7 Bar pressure range across 10 settings, but those figures are not corroborated in the detailed facts. The listing also gives a 650 Millilitres tank while not specifying timer duration, and customer feedback flags possible Australian power-outlet compatibility. Confirm the selected unit's plug and electrical compatibility before purchase.

Who is it for?

A good fit for

People wanting a stationary, corded water flosser for a regular home routine.
Buyers who may use different attachment types for braces, implants or other dental-care needs.

Less suited to

Shoppers who need a cordless or travel-oriented flosser.
Australian buyers who cannot confirm the supplied power connection is compatible with their outlet.

How many attachments and pressure settings are included?

The title claims 7 attachments and 10 pressure settings, but these figures are not confirmed elsewhere in the supplied detailed specifications. Check the selected listing for the exact configuration.

Will it plug into an Australian outlet?
